  • Patent number: 8076104
    Abstract: An improved method for rapid identification of microorganisms is disclosed, along with sequences of PCR primers optimized for this purpose. The primers are designed based on information analysis of sequences from a large number of organism to amplify certain segments of genomic DNA whose sequences are unique among different organisms. The PCR products are compared with a DNA sequence database to obtain the identity of the microorganisms. This approach provides an accurate and fast identification and taxonomic assignment of microbial species.

  • Patent number: 8071301
    Abstract: Method of preparing a biological sample appropriate for use in a subsequent in vitro nucleic acid amplification reaction. The method involves a rapid, transient exposure to alkaline conditions which can be achieved by mixing an alkaline solution with a pH-buffered solution that includes a detergent and the biological sample to be tested for the presence of particular nucleic acid species using in vitro amplification. The invented method advantageously can improve detection of some target nucleic acids without substantially compromising detectability of others. The method is particularly useful for simultaneously preparing RNA and DNA templates that can be used in multiplex amplification reactions.

  • Patent number: 8067205
    Abstract: A method for synthesizing cDNA possessing a consecutive sequence starting with a nucleotide adjacent to a cap structure of mRNA, which comprises (i) a process for annealing a double-stranded DNA primer and an RNA mixture containing mRNA possessing a cap structure, (ii) a process for preparing a conjugate of an mRNA/cDNA heteroduplex and a double-stranded DNA primer by synthesizing the first-strand cDNA primed with the double-stranded DNA primer using reverse transcriptase, and (iii) a process for circularizing the conjugate of the mRNA/cDNA heteroduplex and the double-stranded DNA primer by joining the 3? and 5? ends of the DNA strand containing cDNA using ligase. This method enables us to efficiently synthesize a full-length cDNA possessing a consecutive sequence starting with a transcription-start-site nucleotide from a small amount of RNA by small processes.

  • Patent number: 8053214
    Abstract: An extraction and analysis device includes a microfluidic based collection system that extracts one or more different analytes from a fluid-based sample and an optical analysis system directly coupled to the collection system to perform optical analysis on the one or more collected analytes. The microfluidic based collection system includes microfluidic circuitry for directing a fluid based sample to a purification chip. Analytes collected within the purification chip can be either subsequently removed and analyzed or the analytes can be analyzed directly, while still within the purification chip, using the optical analysis system. The purification chip is preferably comprised of a plurality of pillars, the surface area of each pillar is coated with a specific capture chemistry. The specific capture chemistry is applied by derivitizing the pillars such that a ligand, such as a nucleic acid, an amptimer, or an antibody is attached to each pillar.

  • Patent number: 8034562
    Abstract: The invention relates to a process for isolation of plasmid DNA from biomass by means of an aqueous 2-phase system having a polymer component and a salt component, characterized in that the resuspension of the biomass employed, the alkaline lysis of the biomass, the neutralization of the alkaline lysis batch and the separation of the plasmid DNA from the contaminants are carried out in a single reaction vessel (one-pot process) rendered possible in that the neutralization of the alkaline lysis batch is carried out in one and the same container by addition of potassium phosphate and one component of the aqueous 2-phase system is therefore already present. The second component of the aqueous 2-phase system is a PEG having a molecular weight of the mathematical average of about 600 g/mol to 1,000 g/mol.

  • Patent number: 8034563
    Abstract: A process is provided to generate fluorescent molecules in the presence of target nucleic acids, but not in the absence of that target. Two probes, one bearing moiety A and the other bearing moiety B, bind to the target in a way that brings A and B together. A photon then converts A into A*, which can react with B to form a new species Z that is fluorescent. If A* does not encounter B, then A* reverts to form A. This allows the probe to have another opportunity to be activated should it be later bound near B. In one embodiment, a photoenolization creates A* as a diene; this reacts with a dienophile B in a Diels-Alder reaction. The linker Z may cause the linked probes to bind less tightly to the target, allowing the target to generate many fluorescent products, or be read through by a polymerase.

  • Patent number: 7462705
    Abstract: Five protein families cooperate to form the warhead structure that characterizes enediyne compounds, both chromoprotein enediynes and non-chromoprotein enediynes. The protein families include a polyketide synthase and thioesterase protein which form a polyketide synthase catalytic complex involved in warhead formation in enediynes. Genes encoding a member of each of the five protein families are found in all enediyne biosynthetic loci. The genes and proteins may be used in genetic engineering applications to design new enediyne compounds and in methods to identify new enediyne biosynthetic loci.
